IMPLEMENT POLE CONNECTION.

Applatioii filed September 22, 1922. Serial No. 589,756.

To all lwhom t may concern Be it known that I, HENRY P. ConBiN, a citizen oi the United States, residing at Moline, county oit' Rock Island, State of t Illinois, have invented certain new and uselful Improvements in Implement Pole Connections, of which the following isa specilication. The invention relates to implement pole connections.

Itrelates particularly to pole connections tor use with pullers such as shown in the co-pending application ot Hugo T. Lindgren, Serial No. 536,100, `:filed February 13, 1922.

provide an improved connection for automatically locking a guiding pole to an implement under certain conditions and for automatically releasing it under' other conditions.

A more specific object is to provide an improved and simplified pole connection or a beet puller.

ther objects will herein after appear.

An embodiment or" the invention is illustrated in the drawings, in which,

Figure 1 isa side elevation of a beet puller embodying the invention. y

Figure 2 is a perspective view of the connection betwen the pole and the crank axle.

Figure 3 is a perspective of a rportion of the mechanism showing a slightly modiiied form, the beet-puller being shown in raised position. y F igui'e 4 is a perspective of the mechanism illustrated in VFigure 3, with the parts in the position they occupy when the puller is lowered. l

Figure 5 is a perspective of a modified form with the parts shown in the position they occupy when the beet puller is raised.

Figure Gvis a perspective of the mecha-V nism shown in Figure rwith the parts in the position they occupy when the beet puller is lowered.

The machine comprises, in general, `a tramel supported by a crank axle 2 which carries ground wheels 3 only one of which is shown. Adjustably secured to the frame are arms 4L carrying beet puller tools 5. The machine is raised and lowered by swinging the crank axle 2 by means of a lever 6 pivoted to the frame and connected time, the tongue 1.2 is tree to move laterally and is inactive as a guidingl means.

The present invention 1s directed particularly to the automatic inea-ns for insuring The general object ot the invention is to that the tongue 12 will be rigid with the machine when the latter is raised so that the tongue may be used as a guiding means and for insuring that the tongue will be free to move laterallyv when the machine is lowered so that the steering wheel may be used for guiding purposes.

In order to accomplish this result a bar 15 is connected to and extends rearwardly from a tongue l2. This bar extends through an opening in a loop 16 fixed to the crank axle 2. This loop member is bent at an angle as illustrated in Figure 2 and the opening in it is narrow at one end and Ywide at the other.

The manner in which this mechanism operates will be clear by referring to Figures 3 and 4L, in which theconstruction shown is slightly modified from that illustrated in Figuies 1 and 2, but the operation ot which is the same'. The loop member 16 moves with `the crank axle 2 and when the machine is lowered it occupies the position illustrated in Figure e. When in this position, the bar 15 is positioned at the upper or wide part of the opening in the loop and, consequently, the bar is tree to move to a limited extent sidewise. The pivot 17 of the tongue 12 to the frame ot' the machine is such as to permit the tongue to move in a horizontal plane. In the construction shown this result is by making a hole 18 in the bearing slightly oblong as illustrated in Figures 3 and 4. When the parts are in this position, the tongue 12 can move freely to a limited extent in a horizontal plane. The extent of this movement, can, of course,

be varied 'by varying the size of the opening,

in the loop 16 and the character of the the bar is thus ,prevented and .consequently the tongue is connected rigidly to .the :trame of the machine so that it acts as a guiding member. It acts as the only guiding means since the :steering wheels are, in this `position of the parts, oii the ground and inactive.V

As the lparts move from .the position shown in Figure 4, .to that Vof Figure 3, the bent end of the loop contacts with the end .of bar 15 forcing it vdownwardly into the neck ofthe loop against any tendency of the weight of the pole to raise it.

The modification illustrated in Figures 5 and 6 operatesin thesame general manner as the form hereinbefore described. In this modification, the loop .16 is not bent. In order to insure that the vbar 15 will move in proper relation to the loop member, it is connected by a link 2O with an 'arm 21 forming a part of the bracket connecting the loop to the crank axle. This link prevents the bar 'from moving upwardly from the vposition shown in Figure 5, .that is, it prevents' the front end of the ton-gue from moving downwardly so as .to cause the -bar 15 to move into the wider portion lof opening in tion is for .purposesof illustration only. and

that. modifications may `be made in it without departing from the spirit andr scope of the invention.`

l claim:

In an implement, `a lpole mounted ito swing in 'both "horizontal and vertical planes, an oscillatablesha-ft, and means carried -by the shaft cooperating with the end jof the pole and serving to prevent Vthe pole from swinging in a horizontal plane when the shaft is in one position, but permitting a limited rswinging movement when the shaft is in another position.

2, In an implement, a vpole mounted to swing in both horizontal and vertical planes,

an oscillat-able shaitt, and meas carried by the shaft .cooperating with the end of the pole serving to prevent the pole from swing-V ing in alhorizontal plane when the shaft is in one position and, when the shaft is in another position, permitting a limited movement in a horizontal plane, but preventing the pole it'rom swinging downward. Y

3. In .an implement, a Vpole mounted to swing in both vertical and horizontal planes, an oscillatable shaft, and a loop member `carried by the shaft vserving to prevent the pole from swinging in a horizontal plane when the shaft is in one position and serving, when fthe shaft is in another position, Y to holdthe vend Lot' the pole against vertical movement in one directionybut'permitting a limited amount of horizontal movement.

4. in an implement, guiding pole` mounted tomove in yboth horizontal and vertical planes, a swinging crank axle for raising and ylower-ing the implement, and means carried by the cra-nk axle cooperating with the fend ot' the pole for automatically -lockingjthe pole to the machine when the machine is Vraised and for automatically releasing it to permit the Vpole to move laterally relative to the machine when the ma chine is lowered.

5. In an implement', a guiding pole mounted to move -in both horizontal and verticalv planes, a crank axle, means for swinging thefcrank axle to raise and lower the implement, and an angular loop carried by lthe crank axle and coopera-ting with the end of the tongue for automatically locking the tongue rigidly to the implement when it fis raised and :for automatically releasing the tongue to permit it to move relative "to the implement when the implementisV lowered. 7 Y

6. A beet puller having a klaterally mov- Aable pole, vpivotalY connections for raising and lowering the puller, vand means carried by :the pivotal connections cooperating with the'pole for automatically locking the'pole to the machinewhen it is raised and 'for automatically freeing the pole to permit it to `move relative tothe machine whenV the machine Ais lowered.

7. A beet `puller having a laterally movable pole, a crank axle, means for swinging the crank axle to raise and flower the puller,

and rmeans carriedby the crank axle cooper- Y K ating with the pole for automatically locking 'the `pole rigidly to the machine when the machine is raised and for automatically Y to the machine when itis raised and to automatically releasefthe pole to permit it to move laterally relative tothe machine when the machine is' lowered.

9. A beet puller having steering Wheels, a crank axle, means for swinging the crank axle to raise and lower the puller, the steering Wheels being mounted so as to be out of Contact with the ground when the machine is raised, a Vguiding pole mounted to move 10 laterally relatiye to the puller, and means carried by the crank aXle cooperating with the end of the pole for automatically locking the tongue rigidly to the puller when the latter is' raised and for automatically freeing the pole to render it inoperative as a guiding means when the puller is lowered.
